Emerald Crab Injury

[Instigate]

Anyone seen an injury like this before on an emerald crab? Anything to worry about? I assume it will likely be gone after the next molt right?

It doesn't seem to be bothering the little fella much, it probably will go away the next time it molts.

My guess would be that it scraped it on a rock or something, or possibly got in a scuffle with something.

Yea I envisioned another larger crab grabbing his arm or something maybe causing it. But I thought I should check since I'd never seen an injury like that before.
